SER’S AND MAINTENANCE MANUAL
The cardan shaft supplied with the mower is of the correct size for coupling
with most tractors on the market.
In any case, before starting work for the first time, it is advisable to check its
length.
If adaptation is required, proceed as follows:
Important!
Use only the cardan shaft supplied or recommended, otherwise any warranty
claim or request will be considered null and void.
If the cardan shaft is too long, open the two halves and overlap them; this way
it will be possible to determine how much longer it is in cm.
Cut both tubes of the internal and external cardan shaft to the same length, as
well as their guards.
Clean the cut edges of the tubes with a file, grease them, and reclose the
cardan shaft.
Important!
The maximum work length (L1)
must allow an overlapping of the tubes equal to
half the length of the closed cardan shaft (min. _X).
Always make sure that the cardan shaft is correctly tightened before starting
work
Support chain
Use the chain to prevent rotation of the protection tube.
Make sure that the chain does not hamper the side movements of the cardan
shaft.
